摘要
德南断裂带是山东德南洼陷的主要油气聚集场所 ,精细识别各断层的分布有重要的现实意义。将平面可视化技术应用于德南断裂的精细识别取得了很好的效果 ,已识别出德南断裂是一个向西散开的断裂系 ,它从北到南由 1、 2、 3号北倾断层组成 ;1、 2号断层最终汇聚为一条 ,2号断层下降盘发育 3～ 4条反向补偿断层 ;3号断层是一个小型的断裂系 ,由 5～ 7个北倾断层组成 ,平面上亦向西散开 ;剖面上该断裂系主要反映为向上分开、向下汇聚的帚状断裂系 ;同时还发现了由 3号断裂系控制的断块群。
It is important to recognize the distribution of the faults in Denan fault belt,where there is high potential in oil and gas. The plane visualization is a tool to visualize the 3-D features data which are unseen by an interpreter. By using this technique to the Denan depression it is found out that Denan fault is a fracture system which fans out westward and is composed by faults No.1, No.2 and No.3 from north to south. The fault No.2 merging with the fault No.3 eastward forms a feather fracture system combining with the 3-4 compensation fault on its footwall. The faults No.3 is also a small-sized fracture system composed of 5-7 faults with the same obliquity. All those features are dominantly broom-like on the profiles. And a lot of fault blocks controlled by the fault No.3 are founded. These studies will provide a reliable support for the drillings and reservoir modeling in the future.
